MSNBC is reporting that Secretary of State Hillary Clinton has a blood clot in her head but it's not in her brain.
On Monday Clinton's doctors said she's had no brain damage and she should recover completely.
Clinton, who fainted and suffered a concussion earlier this month, is being treated with blood thinners to help shrink the clot, which is in one of the veins between the brain and her skull.
"In the course of a routine follow-up MRI on Sunday, the scan revealed that a right transverse sinus venous thrombosis had formed," Dr. Lisa Bardack of Mt. Kisco Medical Group in New York and Dr. Gigi El-Bayoumi of George Washington University said in a joint statement.
Doctors also said Clinton is making excellent progress and we are confident she will make a full recovery. She will be released once the medication dose has been established.
